The reset output is active low and open-drain, so it can be wire-ORed with other reset sources on the board. Both the reset timeout period and the voltage threshold are adjustable or selectable via external components or pin strapping, which gives the designer flexibility to match the supervisor to the specific processor's timing and supply rail without changing the part number. ## -40 to 125°C — rated for the tough environments The operating temperature range of -40°C to 125°C (ambient) covers industrial, automotive under-hood, and outdoor telecom enclosures where the board sees wide thermal swings. This is not a commercial-grade supervisor; it is built for the same thermal class as the MCUs and sensors it protects in motor drives, engine control modules, and base station power controllers. ## Package and footprint Housed in a 8-uMAX/uSOP package (also compatible with 8-TSSOP and 8-MSOP footprints), the MAX16998AAUA+T is a surface-mount device that fits compactly on mixed-signal or power-management boards. The 8-pin body is small enough for space-constrained designs but still hand-solderable for prototyping. ## Lifecycle and sourcing reality The MAX16998AAUA+T is listed as Active in production with ROHS3 compliance.","metaTitle":"MAX16998AAUA+T Watchdog Circuit, -40 to 125°C, 8-uMAX","metaDescription":"MAX16998AAUA+T is an active watchdog circuit from Analog Devices with adjustable reset timeout and threshold.
